No matter how much of a rush you are in never drive off with your front wheel still chained to the sidecar chassis. It's bad for your health, bad for your temper and bad for your language (especially important if your wife is within earshot).
Fortunately I had to reverse before I could accelerate away so the damage was limited to my already slightly battered brake disc cover.
Ho hum, We live and learn.

I reckon a Wing with a sidecar or a trike is far easier to steal than a solo. Any thieving scumbag can sit on a Wing with a sidecar or trike even with feet 6" from the floor, while beefy thieving scumbag number 2 pushes it or they ride it away across a field etc. It would require skilled thieving scumbags to do the same with a solo, and there is no such thing.
